Whether the code is on your screen, in a photo, or in front of your camera, you can decode it instantly from any device with a web browser. ScannerQR does all of the work locally — the image is processed on your device and never sent to a server — so even sensitive codes like tickets, payment links and Wi-Fi passwords stay private. FAQ: - Q: Is scanning a QR code online safe? A: With ScannerQR it is. Decoding runs entirely in your browser, so the image and its contents never leave your device or get uploaded to a server. - Q: Do I need to install an app? A: No. Any modern browser on any device can scan QR codes here — there is nothing to download or sign up for. - Q: Can I scan a QR code on a laptop or desktop? A: Yes. Upload the image or paste a screenshot. If your computer has a webcam, you can also use the Camera tab. - Q: Does it work offline? A: Once the page has loaded, the decoder runs locally, so scanning continues to work even with a weak or dropped connection. ### Scan a QR Code From an Image URL: https://www.scannerqr.com/scan-qr-from-image When a QR code is saved as an image — a downloaded JPG, a PNG from a website, or a picture someone sent you — you cannot point a camera at it. Uploading the image to a browser-based reader is the fastest way to decode it. ScannerQR reads the picture on your device and reveals the link or data instantly. FAQ: - Q: How do I scan a QR code from a saved image? A: Upload the image to this page or drag it onto the scanner. The QR code inside the picture is decoded instantly in your browser. - Q: What image formats are supported? A: JPG, JPEG, PNG, WEBP and GIF images all work. - Q: Will my image be uploaded to a server? A: No. The image is processed locally in your browser and never leaves your device. - Q: The code will not scan — what can I do? A: Use a clearer, higher-resolution image, make sure the whole QR code is visible, and avoid heavy blur, glare or cropping. ### Scan a QR Code From a Screenshot URL: https://www.scannerqr.com/scan-qr-from-screenshot You cannot point your phone camera at a QR code that is displayed on the same phone. The trick is to take a screenshot and decode the image instead. ScannerQR reads the screenshot directly, so you can open codes that appear inside apps, emails, websites and chat messages. FAQ: - Q: How do I scan a QR code that is on my own phone screen? A: Take a screenshot of the code, then paste or upload that screenshot here. The scanner decodes the image without needing your camera. - Q: Can I paste a screenshot directly? A: Yes. Copy the screenshot and press Ctrl/Cmd + V on this page to decode it instantly. - Q: Is my screenshot private? A: Completely. Decoding happens in your browser, so the screenshot is never sent anywhere. ### Scan a QR Code With Your Camera URL: https://www.scannerqr.com/scan-qr-from-camera When a QR code is in front of you — on a poster, menu, package or screen — you can scan it live using your device camera right from this page. ScannerQR opens a camera view in your browser, detects the code automatically, and shows the result. Camera frames are processed on your device and never recorded or uploaded. FAQ: - Q: Do I need an app to scan with my camera? A: No. The camera scanner runs in your browser. Just grant camera permission and point at the code. - Q: Why does it ask for camera permission? A: Live scanning needs access to your camera feed. The video is processed on your device only and is never stored or uploaded. - Q: Can I use my laptop webcam? A: Yes. Any device with a camera, including laptops and desktops with a webcam, can scan live. ### Online QR Code Reader URL: https://www.scannerqr.com/online-qr-reader An online QR reader decodes QR codes without any app or account. It works the same on every platform — iPhone, Android, Windows, Mac, Linux and ChromeOS — because everything runs inside the browser you already have. Upload an image, paste a screenshot or use your camera, and the reader reveals the hidden link or data in an instant. FAQ: - Q: What is an online QR reader? A: It is a web-based tool that decodes QR codes without installing an app, working identically across phones and computers. - Q: Is it free to use? A: Yes. Reading QR codes here is completely free with no limits, watermarks or sign-up. - Q: Does it work on iPhone and Android? A: Yes, and on Windows, Mac, Linux and ChromeOS too — anywhere with a modern browser. ### Decode a QR Code URL: https://www.scannerqr.com/decode-qr-code Decoding a QR code means extracting the exact data stored inside it — most often a URL, but also Wi-Fi credentials, contact details, text and more. Because the human eye cannot read a QR code, decoding it first lets you see where it leads before you tap anything. ScannerQR decodes locally in your browser and shows the raw content alongside a safe, clearly labeled action. FAQ: - Q: What does it mean to decode a QR code? A: Decoding extracts the raw data stored in the code — such as a URL or Wi-Fi password — so you can read it directly instead of blindly following it. - Q: Can I see a QR code link without opening it? A: Yes. Decoding reveals the full URL so you can inspect it before deciding whether to visit. - Q: How do I know if the link is safe? A: Decode the code here to read the URL, then use the Safe QR Scanner to analyze it for phishing and other risks. ## QR code generators ### Free URL QR Code Generator URL: https://www.scannerqr.com/url-qr-generator Paste any web address and instantly get a scannable QR code that opens it in the visitor’s browser.
